　　; Start a new pool named 'www'.
　　; the variable $pool can be used in any directive and will be replaced by the
　　; pool name ('www' here)
　　[www]
　　; Per pool prefix
　　; It only applies on the following directives:
　　; - 'access.log'
　　; - 'slowlog'
　　; - 'listen' (unixsocket)
　　; - 'chroot'
　　; - 'chdir'
　　; - 'php_values'
　　; - 'php_admin_values'
　　; When not set, the global prefix (or /usr) applies instead.
　　; Note: This directive can also be relative to the global prefix.
　　; Default Value: none
　　;prefix = /path/to/pools/$pool
　　; Unix user/group of processes
　　; Note: The user is mandatory. If the group is not set, the default user's group
　　;       will be used.
　　user = www-data
　　group = www-data
　　; The address on which to accept FastCGI requests.
　　; Valid syntaxes are:
　　;   'ip.add.re.ss:port'    - to listen on a TCP socket to a specific IPv4 address on
　　;                            a specific port;
　　;   '[ip:6:addr:ess]:port' - to listen on a TCP socket to a specific IPv6 address on
　　;                            a specific port;
　　;   'port'                 - to listen on a TCP socket to all addresses
　　;                            (IPv6 and IPv4-mapped) on a specific port;
　　;   '/path/to/unix/socket' - to listen on a unix socket.
　　; Note: This value is mandatory.
　　listen = /run/php/php7.2-fpm.sock
　　; Set listen(2) backlog.
　　; Default Value: 511 (-1 on FreeBSD and OpenBSD)
　　;listen.backlog = 511
　　; Set permissions for unix socket, if one is used. In Linux, read/write
　　; permissions must be set in order to allow connections from a web server. Many
　　; BSD-derived systems allow connections regardless of permissions.
　　; Default Values: user and group are set as the running user
　　;                 mode is set to 0660
　　listen.owner = www-data
　　listen.group = www-data
　　;listen.mode = 0660
　　; When POSIX Access Control Lists are supported you can set them using
　　; these options, value is a comma separated list of user/group names.
　　; When set, listen.owner and listen.group are ignored
　　;listen.acl_users =
　　;listen.acl_groups =
　　; List of addresses (IPv4/IPv6) of FastCGI clients which are allowed to connect.
　　; Equivalent to the FCGI_WEB_SERVER_ADDRS environment variable in the original
　　; PHP FCGI (5.2.2+). Makes sense only with a tcp listening socket. Each address
　　; must be separated by a comma. If this value is left blank, connections will be
　　; accepted from any ip address.
　　; Default Value: any
　　;listen.allowed_clients = 127.0.0.1
　　; Specify the nice(2) priority to apply to the pool processes (only if set)
　　; The value can vary from -19 (highest priority) to 20 (lower priority)
　　; Note: - It will only work if the FPM master process is launched as root
　　;       - The pool processes will inherit the master process priority
　　;         unless it specified otherwise
　　; Default Value: no set
　　; process.priority = -19
　　; Set the process dumpable flag (PR_SET_DUMPABLE prctl) even if the process user
　　; or group is differrent than the master process user. It allows to create process
　　; core dump and ptrace the process for the pool user.
　　; Default Value: no
　　; process.dumpable = yes
　　; Choose how the process manager will control the number of child processes.
　　; Possible Values:
　　;   static  - a fixed number (pm.max_children) of child processes;
　　;   dynamic - the number of child processes are set dynamically based on the
　　;             following directives. With this process management, there will be
　　;             always at least 1 children.
　　;             pm.max_children      - the maximum number of children that can
　　;                                    be alive at the same time.
　　;             pm.start_servers     - the number of children created on startup.
　　;             pm.min_spare_servers - the minimum number of children in 'idle'
　　;                                    state (waiting to process). If the number
　　;                                    of 'idle' processes is less than this
　　;                                    number then some children will be created.
　　;             pm.max_spare_servers - the maximum number of children in 'idle'
　　;                                    state (waiting to process). If the number
　　;                                    of 'idle' processes is greater than this
　　;                                    number then some children will be killed.
　　;  ondemand - no children are created at startup. Children will be forked when
　　;             new requests will connect. The following parameter are used:
　　;             pm.max_children           - the maximum number of children that
　　;                                         can be alive at the same time.
　　;             pm.process_idle_timeout   - The number of seconds after which
　　;                                         an idle process will be killed.
　　; Note: This value is mandatory.
　　pm = dynamic
　　; The number of child processes to be created when pm is set to 'static' and the
　　; maximum number of child processes when pm is set to 'dynamic' or 'ondemand'.
　　; This value sets the limit on the number of simultaneous requests that will be
　　; served. Equivalent to the ApacheMaxClients directive with mpm_prefork.
　　; Equivalent to the PHP_FCGI_CHILDREN environment variable in the original PHP
　　; CGI. The below defaults are based on a server without much resources. Don't
　　; forget to tweak pm.* to fit your needs.
　　; Note: Used when pm is set to 'static', 'dynamic' or 'ondemand'
　　; Note: This value is mandatory.
　　pm.max_children = 500
　　; The number of child processes created on startup.
　　; Note: Used only when pm is set to 'dynamic'
　　; Default Value: min_spare_servers + (max_spare_servers - min_spare_servers) / 2
　　pm.start_servers = 250
　　; The desired minimum number of idle server processes.
　　; Note: Used only when pm is set to 'dynamic'
　　; Note: Mandatory when pm is set to 'dynamic'
　　pm.min_spare_servers = 50
　　; The desired maximum number of idle server processes.
　　; Note: Used only when pm is set to 'dynamic'
　　; Note: Mandatory when pm is set to 'dynamic'
　　pm.max_spare_servers = 450
　　; The number of seconds after which an idle process will be killed.
　　; Note: Used only when pm is set to 'ondemand'
　　; Default Value: 10s
　　;pm.process_idle_timeout = 10s;
　　; The number of requests each child process should execute before respawning.
　　; This can be useful to work around memory leaks in 3rd party libraries. For
　　; endless request processing specify '0'. Equivalent to PHP_FCGI_MAX_REQUESTS.
　　; Default Value: 0
　　;pm.max_requests = 500
　　; The URI to view the FPM status page. If this value is not set, no URI will be
　　; recognized as a status page. It shows the following informations:
　　;   pool                 - the name of the pool;
　　;   process manager      - static, dynamic or ondemand;
　　;   start time           - the date and time FPM has started;
　　;   start since          - number of seconds since FPM has started;
　　;   accepted conn        - the number of request accepted by the pool;
　　;   listen queue         - the number of request in the queue of pending
　　;                          connections (see backlog in listen(2));
　　;   max listen queue     - the maximum number of requests in the queue
　　;                          of pending connections since FPM has started;
　　;   listen queue len     - the size of the socket queue of pending connections;
　　;   idle processes       - the number of idle processes;

　　;   total processes      - the number of idle + active processes;
　　;   max active processes - the maximum number of active processes since FPM
　　;                          has started;
　　;   max children reached - number of times, the process limit has been reached,
　　;                          when pm tries to start more children (works only for
　　;                          pm 'dynamic' and 'ondemand');
　　; Value are updated in real time.
　　; Example output:
　　;   pool:                 www
　　;   process manager:      static
　　;   start time:           01/Jul/2011:17:53:49 +0200
　　;   start since:          62636
　　;   accepted conn:        190460
　　;   listen queue:         0
　　;   max listen queue:     1
　　;   listen queue len:     42
　　;   idle processes:       4
　　;   active processes:     11
　　;   total processes:      15
　　;   max active processes: 12
　　;   max children reached: 0
　　;
　　; By default the status page output is formatted as text/plain. Passing either
　　; 'html', 'xml' or 'json' in the query string will return the corresponding
　　; output syntax. Example:
　　;   http://www.foo.bar/status
　　;   http://www.foo.bar/status?json
　　;   http://www.foo.bar/status?html
　　;   http://www.foo.bar/status?xml
　　;
　　; By default the status page only outputs short status. Passing 'full' in the
　　; query string will also return status for each pool process.
　　; Example:
　　;   http://www.foo.bar/status?full
　　;   http://www.foo.bar/status?json&full
　　;   http://www.foo.bar/status?html&full
　　;   http://www.foo.bar/status?xml&full
　　; The Full status returns for each process:
　　;   pid                  - the PID of the process;
　　;   state                - the state of the process (Idle, Running, ...);
　　;   start time           - the date and time the process has started;
　　;   start since          - the number of seconds since the process has started;
　　;   requests             - the number of requests the process has served;
　　;   request duration     - the duration in µs of the requests;
　　;   request method       - the request method (GET, POST, ...);
　　;   request URI          - the request URI with the query string;
　　;   content length       - the content length of the request (only with POST);
　　;   user                 - the user (PHP_AUTH_USER) (or '-' if not set);
　　;   script               - the main script called (or '-' if not set);
　　;   last request cpu     - the %cpu the last request consumed
　　;                          it's always 0 if the process is not in Idle state
　　;                          because CPU calculation is done when the request
　　;                          processing has terminated;
　　;   last request memory  - the max amount of memory the last request consumed
　　;                          it's always 0 if the process is not in Idle state
　　;                          because memory calculation is done when the request
　　;                          processing has terminated;
　　; If the process is in Idle state, then informations are related to the
　　; last request the process has served. Otherwise informations are related to
　　; the current request being served.
　　; Example output:
　　;   ************************
　　;   pid:                  31330
　　;   state:                Running
　　;   start time:           01/Jul/2011:17:53:49 +0200

　　;   last request cpu:     0.00
　　;   last request memory:  0

　　; Note: There is a real-time FPM status monitoring sample web page available
　　;       It's available in: /usr/share/php/7.2/fpm/status.html
　　;
　　; Note: The value must start with a leading slash (/). The value can be
　　;       anything, but it may not be a good idea to use the .php extension or it
　　;       may conflict with a real PHP file.
　　; Default Value: not set
　　;pm.status_path = /status
　　; The ping URI to call the monitoring page of FPM. If this value is not set, no
　　; URI will be recognized as a ping page. This could be used to test from outside
　　; that FPM is alive and responding, or to
　　; - create a graph of FPM availability (rrd or such);
　　; - remove a server from a group if it is not responding (load balancing);
　　; - trigger alerts for the operating team (24/7).
　　; Note: The value must start with a leading slash (/). The value can be

　　;catch_workers_output = yes
　　; Clear environment in FPM workers
　　; Prevents arbitrary environment variables from reaching FPM worker processes
　　; by clearing the environment in workers before env vars specified in this
　　; pool configuration are added.
　　; Setting to "no" will make all environment variables available to PHP code
　　; via getenv(), $_ENV and $_SERVER.
　　; Default Value: yes
　　;clear_env = no
　　; Limits the extensions of the main script FPM will allow to parse. This can
　　; prevent configuration mistakes on the web server side. You should only limit
　　; FPM to .php extensions to prevent malicious users to use other extensions to
　　; execute php code.
　　; Note: set an empty value to allow all extensions.
　　; Default Value: .php

　　; Additional php.ini defines, specific to this pool of workers. These settings
　　; overwrite the values previously defined in the php.ini. The directives are the
　　; same as the PHP SAPI:
　　;   php_value/php_flag             - you can set classic ini defines which can
　　;                                    be overwritten from PHP call 'ini_set'.
　　;   php_admin_value/php_admin_flag - these directives won't be overwritten by
　　;                                     PHP call 'ini_set'
　　; For php_*flag, valid values are on, off, 1, 0, true, false, yes or no.
　　; Defining 'extension' will load the corresponding shared extension from
　　; extension_dir. Defining 'disable_functions' or 'disable_classes' will not
　　; overwrite previously defined php.ini values, but will append the new value
　　; instead.
　　; Note: path INI options can be relative and will be expanded with the prefix
　　; (pool, global or /usr)
　　; Default Value: nothing is defined by default except the values in php.ini and
　　;                specified at startup with the -d argument
　　;php_admin_value[sendmail_path] = /usr/sbin/sendmail -t -i -f www@my.domain.com
　　;php_flag[display_errors] = off
　　;php_admin_value[error_log] = /var/log/fpm-php.www.log
　　;php_admin_flag[log_errors] = on
　　;php_admin_value[memory_limit] = 32M
　　以上为我在一个2核8g的Linux服务器上的配置
　　其中如果是采用dynamic模式的话需要注意：
　　pm.max_children > pm.max_spare_servers
　　pm.min_spare_servers < pm.start_servers < pm.max_spare_servers
